Authr the Deep-Minded

Authr the Deep-Minded (672-735) was the daughter of Ivar Vidfamne, the wife of Hroerekr Ringslinger, and the mother of Harald Wartooth. She was in love with Hroerekr's brother Helgi the Sharp, so her father told Hroerekr about this, leading to Hroerekr slaying Helgi. Ivar took advantage of this and conquered Hroerekr's lands for himself. Authr died in 735, six years after her son became king of Scandinavia.
